Wet-mixed Mortar Production
Wet-mixed mortar production involves the on-site or centralized mixing of various ingredients, including cement, aggregates, water, and additives, to create a ready-to-use mortar mixture. Unlike dry-mixed mortar, where the ingredients are pre-mixed and stored in a dry state, wet-mixed mortar is mixed with water just before application.
Steps of Wet-Mixed Mortar Production
Cement, aggregates, and additives are proportioned according to the desired mix design. The ratios are determined based on the specific application requirements.
The ingredients are mixed using mechanical mixing equipment, such as drum mixers, pan mixers, or batch mixers. Water is added gradually to achieve the desired consistency.
Testing and Adjustment
The freshly mixed mortar is tested for workability, consistency, and other properties. Adjustments can be made by adding more water or dry ingredients as needed.
Once the mortar reaches the desired properties, it is immediately applied to the construction surface. This could involve various tasks like bricklaying, plastering, or masonry work.
Advantages of Wet-Mixed Mortar Production
